Актуальность исследования Гусар-Шабранского (Девечинского) прогиба, помимо основной фундаментальной – изучение особенностей формирования и геодинамики, определяется и практическими задачами, связанными с перспективами обнаружения нефтяных и газовых месторождений и выявления геодинамической опасности для нефтепровода Баку-Новороссийск, водопроводов Шоллар, Тахтакёрпю и других инфраструктур в этом регионе.

В статье дается 2D гравитационная модель профиля Самур–Баку, расположенного на западном побережье Каспийского моря, построенная с использованием неоднородной плотностной модели, и геодинамические характеристики профиля. 2D гравитационная модель составлена методом подбора плотностных границ. Уточнены границы базальта (28-32 км) и Moxo (47-57 км). Вдоль профиля проанализированы кривые скорости современных вертикальных и горизонтальных движений, и идентифицированы зоны накопления напряжения. Определены радиусы очагов и магнитуды землетрясений, создавших дополнительные ощутимые напряжения, которые влияют на геодинамические условия профиля.
